This can be easily accomplished if you change your concept of
data collection. Instead of collecting the absolute TPoint( X,Y ),
Assume that the starting position is the center of the screen
and then collect points relative to the previouse point. For
example, if the previouse point was 10,10 and the new point
is 8,12, the data point would be -2,2 and the previouse point
would become 8,12.

Now all you have to do is add logic to your code to handle
when the mouse hits the limits of the window. Just reposition
it back to the center of the screen and set the previouse point
to the center of the screen as well.

As for mouse movement in terms of GUI, you could paint
a simulated mouse at the center of the screen and set the
Screen::Cursor to crNone so that it appears that the mouse
isn't moving at all.
